Nissan's SR20 engine with the VVL cylinder head. while it wasn't offered stock in any U.S. cars. it is often imported from failed Japanese inspections that said the engine was no good, when over in the U.S. it is considered brand new.
the SR20VE produced 186HP @ 7000RPM and 144 ft-lbf at 6000rpm
the SR16VE-N1 cams are often considered an upgrade due to the engine being able to rev to 8600rpms with the N1 cams.
guy1: dude get over here i just finished swapping a SR20VE into my g20
guy2: sweet now we just need to get some N1 cams.
